This Prague City Gallery exhibition is part of a joint project co-organized with the Brno House of Arts where its first part was held in autumn 2017. The aim of the given cooperation is to present the oeuvre of the artist professing Action Art and Video Art in as complex way as possible. The first, Brno part, introduced to Ruller’s works from between 1974 to present and was based on the sphere of Action Art and its representation in the form of static paintings, objects, installations and texts. The Prague part, employing specific exhibition and visual concept, will present a partially identical segment of the artist’s oeuvre, but via different prism, highlighting the element of time; it will therefore mainly concentrate on his works from the sphere of moving image. The main goal of the exhibition is to integrate two essential positions present in Ruller’s oeuvre: on one hand, an original event (performance) developing in an authentic context of time and space and, on the other hand, the artist’s characteristic treatment of records and archive documents as a live grounds for new and constantly updated work and for exploring new forms of re-mediation, re-contextualization and re-presentation of a work of art.
